This is my first project that i am going to do it all alone. I am a beginner and i have only theoretical knowledge i wish to develop myself better by doing many projects. So i would like to get few things clarified.

In the senor data sheet, I have seen that voltage supply is 4,9...30 VDC. What does that mean? Is it like the sensor needs a voltage supply of 30 V to function?

How to connect the sensor output cable to raspberry pi physically? Do i need to use any connector like thing to connect the sensor with raspberry Pi? or is there any other way to connect it perfectly?

The sensor output is an analog voltage beween 0 and 10 Volts. You can't connect that directly to a Raspberry Pi because there are no analog inputs on a RPi. You need an external analog to digital converter circuit. You should use at least 12-bit ADC to match the resolution of the sensor.

You have told that a supply of 4.9 volts is enough to power the sensor. Can you please give me an idea of how to power the sensor? I mean is it possible to use an external power supply for sensor ?

The analog output of the sensor is from 0-10 V. Also, I have read that the raspberry pi can withstand only 3.3. volts , and it will blow the pi if the voltage exceeds. is it true? if true, is there any other way to connect it?

Resistor voltage divider will get the 10V down to a voltage a 3V3 i2C ADC can read.

So the sensor output has to be connected to Voltage divider and then it has to be connected to ADC. What does I2C mean? is there any programming that i should use to make i2c connection?
Can you please explain this a little bit more?

Thank you very much for your Quick response. I really appreciate it. You have told that a supply of 4.9 volts is enough to power the sensor. Can you please give me an idea of how to power the sensor? I mean is it possible to use an external power supply for sensor ?

i know that voltage divider cirucit can be made easily by chossing correct resistors. But i would like to know is there any ready made chips to do this job so that it can be connected very easily with raspberry pi.

Not really. You "could" find an ADC that is capable of reading 10V (max) which can also communicate with the Pi at 3.3v (but I don't think any exist, not that I can find anyway)
Generally speaking, people use either passive components (voltage dividers) or active components (operational amplifiers etc) to change the voltage to something that is in the correct range.

This project is well beyond your capability, due to your lack of understanding of basic electronics
A course in basic electronics is you next step, You know what you want. But lack the ability to put
it in to practice
